[0002] In practical applications of dishwashers, for cleaning deep-shaped tableware such as cups and baby bottles, a special spray arm is usually installed to reach inside the tableware for rinsing, in order to improve cleaning effectiveness. However, during the washing process, the impact force of the water jets from the spray arm can cause the tableware to shake. This shaking not only prevents the water from evenly covering the inner walls of the tableware, reducing cleaning efficiency, but may also cause the tableware to collide with each other or impact the internal structure of the dishwasher, resulting in damage to the tableware or dishwasher components.

[0003] In existing technologies, some dishwashers use clamping structures to hold tableware in place, using the clamping force to limit tableware displacement and thus ensure stability during the washing process. However, the clamping structures in existing solutions are relatively complex and inconvenient to install. Therefore, the performance of the spray arm assembly used to hold and clean deep-shaped tableware needs further improvement. Utility Model Content

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0043] The following is for reference. Figures 1-6 The spray arm assembly 10 according to a first aspect embodiment of the present invention is described.

[0044] like Figures 2-4 As shown, the spray arm assembly 10 according to the first aspect of the present invention includes: a spray arm 11 and a clamping member 12.

[0045] Specifically, the spray arm 11 is along a first direction (e.g., Figure 2 and Figure 4 The spray arm 11 extends in the vertical direction shown in the figure, and one end of the spray arm 11 has a spray hole 111; the clamping member 12 includes a clamping body 121 and an elastic arm 122 connected to the clamping body 121, the clamping body 121 extending in a first direction (e.g., vertical direction), and one end of the spray arm 11 has a spray hole 111 formed thereon; the clamping member 12 includes a clamping body Figure 2 and Figure 4 Extending in the vertical direction shown, the clamping body 121 has a first end 121a and a second end 121b spaced apart in the first direction. Both the first end 121a and the second end 121b are open and respectively sleeved on the outside of the spray arm 11. The clamping body 121 and the elastic arm 122 are adapted to clamp on the inner and outer surfaces of the side wall of the tableware to be cleaned, so that the end of the spray arm 11 with the spray hole 111 extends into the tableware to be cleaned. The clamping body 121 and the spray arm 11 are detachably connected.

[0046] like Figure 4 As shown, the spray arm 11 is a tubular structure extending vertically. A spray hole 111 is formed at the upper end of the spray arm 11. There can be one or more spray holes 111, and when there are multiple spray holes 111, they can be arranged at intervals. The lower end of the spray arm 11 is used to connect to a water pipe 30 for water supply.

[0047] The clamping member 12 is disposed on the spray arm 11 and includes a clamping body 121 and an elastic arm 122. The clamping body 121 is formed into a cylindrical shape that extends in the vertical direction and is open at both ends. The lower end of the clamping body 121 is formed into a first end 121a, and the upper end of the clamping body 121 is formed into a second end 121b. The clamping body 121 is sleeved and fixed on the outside of the spray arm 11. The elastic arm 122 is a cantilever shape that can undergo elastic deformation. The lower end of the elastic arm 122 is connected to the first end 121a of the clamping body 121, and the other end is used to cooperate with the second end 121b of the clamping body 121 to clamp the tableware to be cleaned. The tableware to be cleaned can be a cup or a baby bottle with a certain depth.

[0048] When cleaning tableware of a certain depth is required, the tableware to be cleaned can be inverted and placed on the side of the spray arm 11 where the spray holes 111 are located, so that the opening of the tableware faces the spray arm assembly 10. Then, the side wall of the tableware is clamped between the elastic arm 122 and the clamping body 121. At this time, the spray arm 11 and the clamping body 121 can extend into the inside of the tableware to be cleaned, so that the spray holes 111 can spray water directly onto the inner wall surface of the tableware to be cleaned, thereby rinsing the inside of the tableware and achieving effective cleaning of tableware of a certain depth, thus improving the cleaning effect.

[0049] Since the nozzle 111 is located inside the tableware to be cleaned and washes the inner wall of the tableware, the sprayed water has a certain impact force on the tableware to be cleaned, which may cause the tableware to shake during the cleaning process. However, the clamping member 12 of this embodiment clamps the side wall of the tableware to be cleaned by clamping the main body 121 and the elastic arm 122, so that the tableware to be cleaned can be stably fixed in the clamping position during the rinsing process and will not shake. This can improve the cleaning effect and also prevent the tableware from being damaged by collision due to shaking.

[0050] Since the first end 121a and the second end 121b of the clamping body 121 in this embodiment are arranged at intervals in the first direction, and the first end 121a and the second end 121b are respectively sleeved on the spray arm 11, the first end 121a and the second end 121b are sleeved at intervals on the spray arm 11, which can make the clamping body 121 more stably fixed on the spray arm 11, reduce the probability of the clamping member 12 shaking relative to the spray arm 11, thereby reducing the probability of the tableware to be cleaned fixed on the clamping member 12 shaking, and improving the stability of clamping the tableware to be cleaned.

[0051] Meanwhile, when the tableware to be cleaned is clamped on the clamping member 12, since the first end 121a and the second end 121b are spaced apart on the spray arm 11, during the cleaning process, when the water flow impacts the tableware, the first end 121a and the second end 121b can transmit the force acting on the tableware to the spray arm 11 and the water pipe 30 connected to the spray arm 11. Thus, the force can be dispersed, the pressure at a single connection point between the clamping body 121 and the spray arm 11 can be reduced, the wear at the connection point between the clamping body 121 and the spray arm 11 can be reduced, and the service life of the spray arm assembly 10 can be improved.

[0052] In addition, the first end 121a and the second end 121b of the clamping body 121 are both sleeved on the spray arm 11, which can increase the connection area between the clamping body 121 and the spray arm 11, thereby improving the reliability and stability of the connection between the clamping body 121 and the spray arm 11, reducing stress concentration, and extending service life.

[0053] Furthermore, the clamping component 12 is detachably connected to the spray arm 11. Specifically, the clamping body 121 is detachably connected to the spray arm 11. For example, the clamping body 121 and the spray arm 11 can be connected by fasteners, by threaded connection, by snap-fit ​​connection, or by magnetic attraction. This facilitates the installation and removal of the clamping component 12 and the spray arm 11, reduces assembly difficulty, improves assembly efficiency, and also facilitates the maintenance and replacement of the clamping component 12, reducing the maintenance cost of the spray arm assembly 10.

[0054] According to the embodiment of the present invention, the spray arm assembly 10, by providing a clamping member 12 for clamping the tableware to be cleaned, not only can the tableware be effectively fixed, but the spray nozzles 111 of the spray arm 11 can also easily extend into the tableware, improving the cleaning effect. By making the clamping member 12 detachably connected to the spray arm 11, the assembly and disassembly efficiency between the spray arm 11 and the clamping member 12 can be improved, facilitating the maintenance and replacement of the clamping member 12, and reducing the assembly difficulty and maintenance cost of the spray arm assembly 10. By sleeved on the first end 121a and the second end 121b of the clamping body 121 onto the spray arm 11, the connection stability and reliability between the clamping body 121 and the spray arm 11 can be improved, thereby improving the stability of clamping the tableware to be cleaned.

[0055] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the first direction is the vertical direction. The clamping body 121 is formed as a cylindrical shape extending in the vertical direction and open at both ends. The lower end of the clamping body 121 is formed as the first end 121a, and the upper end of the clamping body 121 is formed as the second end 121b. The elastic arm 122 is connected to the first end 121a, and the second end 121b is disposed adjacent to the nozzle 111. "The second end 121b is disposed adjacent to the nozzle 111" means that the second end 121b is located on the side of the first end 121a facing the nozzle 111, or that the second end 121b is closer to the nozzle 111 than the first end 121a.

[0056] In this embodiment, the clamping body 121 is configured as a cylindrical shape extending vertically, with its upper and lower ends respectively fitted onto the spray arm 11. The lower end of the elastic arm 122 is connected to the lower end of the clamping body 121, and the upper end of the elastic arm 122 cooperates with the upper end of the clamping body 121 to clamp the tableware to be cleaned. In this way, when clamping the tableware to be cleaned, the tableware can be inverted, with the opening of the tableware aligned with the spray arm 11, and the side wall of the tableware inserted between the clamping body 121 and the elastic arm 122. This optimizes the structure of the clamping member 12, facilitates the clamping of the tableware to be cleaned, and improves the stability and reliability of the clamping member 12 in clamping the tableware to be cleaned.

[0057] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the clamping body 121 is snapped into connection with the spray arm 11. For example, the clamping body 121 may be provided with a first clamping part, and the spray arm 11 may be provided with a second clamping part. The first clamping part and the second clamping part cooperate with each other to realize the snapping connection between the clamping body 121 and the spray arm 11. The first clamping part may be a card hole 1211, a card groove, a card protrusion 112, a card hook, a card block, etc., which are adapted to the first clamping part.

[0058] This embodiment simplifies the connection structure between the clamping body 121 and the spray arm 11 by snapping the clamping body 121 with the spray arm 11, thereby improving assembly efficiency and reducing the production and maintenance costs of the spray arm assembly 10.

[0059] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a protruding locking protrusion 112 is formed on the outer peripheral surface of the spray arm 11, and a locking hole 1211 is formed on the clamping body 121, with the locking protrusion 112 fitting into the locking hole 1211. This further simplifies the locking structure between the spray arm 11 and the clamping body 121, facilitates processing and manufacturing, improves production efficiency, and increases assembly efficiency.

[0060] In some examples, the 1211 can be a blind hole; in other examples, such as... Figure 4 As shown, the clasp 1211 penetrates the clamping body 121 radially, that is, the clasp 1211 is formed as a through hole penetrating the clamping body 121 along the wall thickness direction of the clamping body 121. This reduces the machining difficulty of the clasp 1211.

[0061] In some examples, the gauging hole 1211 is along the first direction (e.g.) Figure 4 The clamping body 121 extends into a long strip shape (as shown in the vertical direction), and the protrusion 112 abuts against the inner wall of the end of the clamping hole 1211 opposite to the nozzle 111. This reduces the rigidity of the clamping body 121, allowing the protrusion 112 to easily engage with the clamping hole 1211 from the inside of the clamping body 121, and restricts the movement of the clamping body 121 along the first direction.

[0062] In some examples, the locking hole 1211 has a first inner wall and a second inner wall arranged opposite each other in a first direction. The first inner wall is disposed on the side of the second inner wall opposite to the nozzle 111. In the circumferential direction of the spray arm 11, the first inner wall extends along an arcuate curve opposite to the protrusion of the second inner wall, i.e., the first inner wall is an arcuate cylindrical surface opposite to the protrusion of the second inner wall. The surface of the locking protrusion 112 opposite to the nozzle 111 is adapted to the shape of the first inner wall. The second inner wall also extends along an arcuate curve opposite to the protrusion of the first inner wall.

[0063] Furthermore, the two sides of the locking protrusion 112 on the circumferential direction of the spray arm 11 respectively abut against the two side walls of the locking hole 1211 on the circumferential direction of the spray arm 11. Thus, the engagement between the locking protrusion 112 and the side wall of the locking hole 1211 can restrict the rotation of the clamping body 121 and the spray arm 11 in the circumferential direction of the spray arm 11, thereby improving the reliability and stability of the clamping body 121 and the spray arm 11.

[0064] In some examples, the surface of the latching protrusion 112 facing the nozzle 111 in the first direction has a guide slope, and in the direction from the water inlet end of the spray arm 11 towards the nozzle 111, the guide slope extends obliquely toward the inside of the spray arm 11. Thus, the guide slope can guide the latching protrusion 112 into the inside of the clamping body 121, reducing assembly difficulty and improving assembly efficiency.

[0065] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the clamping body 121 is provided with a first positioning structure, and the spray arm 11 is provided with a second positioning structure that cooperates with the first positioning structure for positioning. The positioning cooperation between the first and second positioning structures can further improve the assembly efficiency between the clamping body 121 and the spray arm 11.

[0066] In some examples, the first positioning structure may include: positioning groove 1212, positioning hole, positioning post 113, positioning pin and / or positioning block, etc., and the second positioning structure may include positioning groove 1212, positioning hole, positioning post 113, positioning pin and / or positioning block, etc., adapted to the first positioning structure.

[0067] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, one of the clamping body 121 and the spray arm 11 has a positioning groove 1212 and the other has a positioning post 113, with the positioning post 113 fitting within the positioning groove 1212. For example, when the positioning groove 1212 is formed on the clamping body 121, the positioning post 113 is formed on the spray arm 11; conversely, when the positioning post 113 is formed on the clamping body 121, the positioning groove 1212 is formed on the spray arm 11. In this embodiment, the positioning post 113 and the positioning groove 1212 are positioned together, which allows for the positioning of the relative positions of the clamping body 121 and the spray arm 11 in the circumferential direction of the clamping body 121, thus improving assembly efficiency.

[0068] like Figure 4 As shown, the first positioning structure on the clamping body 121 includes a positioning groove 1212, and the second positioning structure on the spray arm 11 includes a positioning post 113. The number of positioning grooves 1212 can be one or multiple ones spaced apart. The number of positioning posts 113 corresponds one-to-one with the number of positioning grooves 1212.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the positioning groove 1212 is formed at the first end 121a of the clamping body 121 and extends through the end edge of the first end 121a of the clamping body 121. This simplifies the structure of the positioning groove 1212, facilitates its processing and forming, and also facilitates the positioning and engagement of the positioning groove 1212 with the positioning post 113.

[0070] like Figure 4 As shown, the positioning groove 1212 is formed at the lower end of the clamping body 121 and has an upward recessed notch shape from the lower end of the clamping body 121. The positioning groove 1212 penetrates the clamping body 121 along the wall thickness direction of the clamping body 121.

[0071] Furthermore, the positioning groove 1212 is U-shaped, and the sidewall and top wall of the positioning groove 1212 are connected by an arc. The shape of the positioning post 113 is adapted to the shape of the positioning groove 1212. When the positioning post 113 is fitted into the positioning groove 1212, it can position the clamping body 121 and the spray arm 11 in the circumferential direction of the spray arm 11, which facilitates the alignment of the locking protrusion 112 and the locking hole 1211 in the axial direction of the spray arm 11, and facilitates the locking protrusion 112 to be engaged in the locking hole 1211, thereby improving assembly efficiency.

[0072] Furthermore, the positioning groove 1212 and the locking hole 1211 are axially aligned and spaced apart on the clamping body 121, and the positioning post 113 and the locking protrusion 112 are axially aligned and spaced apart on the spray arm 11. When the clamping body 121 is mounted on the spray arm 11, the portion of the shell wall of the clamping body 121 located between the positioning groove 1212 and the locking hole 1211 is precisely locked between the locking protrusion 112 and the positioning post 113. At this time, the locking protrusion 112 and the positioning post 113 can cooperate with each other to restrict the upward and downward movement of the clamping body 121 relative to the spray arm 11, improving the fixing reliability between the clamping body 121 and the spray arm 11.

[0073] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the spray hole 111 is formed on the end face of one end of the spray arm 11 (e.g., Figure 4 On the upper end face of the spray arm 11 shown, the end face of one end of the spray arm 11 (e.g.) Figure 4 The upper end face of the spray arm 11 shown has a recessed groove 114, which penetrates the outer peripheral surface of the spray arm 11 and clamps the second end 121b of the main body 121 (e.g., Figure 4 The upper end of the clamping body 121 shown has a positioning protrusion 1213 extending radially inward along the clamping body 121, and the positioning protrusion 1213 fits into the groove 114.

[0074] For example, when the clamping body 121 is installed on the spray arm 11, the positioning protrusion 1213 can abut against the bottom wall of the groove 114. At this time, the positioning protrusion 1213 and the bottom wall of the groove 114 cooperate with each other to achieve the positioning of the clamping body 121 and the spray arm 11 in the axial direction of the spray arm 11, thereby improving the assembly efficiency between the clamping body 121 and the spray arm 11.

[0075] In some examples, the positioning protrusion 1213 can be connected to the upper edge of the spray arm 11, and the positioning protrusion 1213 can be connected to the peripheral wall of the clamping body 121 by an arc. This simplifies the structure of the clamping body 121 and facilitates the machining of the positioning protrusion 1213.

[0076] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the groove 114 extends in a ring shape along the circumference of the spray hole 111, and the positioning protrusion 1213 extends in a ring shape along the circumference of the clamping body 121. This improves the structural strength of the positioning protrusion 1213, and when the positioning protrusion 1213 engages with the bottom wall of the groove 114, the force between the positioning protrusion 1213 and the spray arm 11 is evenly distributed in the circumferential direction of the spray arm 11.

[0077] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the elastic arm 122 is along a first direction (e.g., Figure 4 Extending in the vertical direction shown, the elastic arm 122 extends away from the nozzle 111 at one end (as shown in the figure). Figure 4 The lower end of the elastic arm 122 shown is fixed to the clamping body 121, and the other end of the elastic arm 122 (as shown) is fixed to the clamping body 121. Figure 4 The upper end of the elastic arm 122 shown has a clamping protrusion 1221 that protrudes toward the clamping body 121, and the clamping protrusion 1221 is adapted to abut against the outer surface of the tableware to be cleaned.

[0078] In this embodiment, by providing a clamping protrusion 1221, during the process of the tableware being cleaned extending between the elastic arm 122 and the clamping body 121, the clamping protrusion 1221 more easily contacts the outer surface of the tableware, thereby improving the reliability and stability of the clamping member 12 in holding the tableware. During product design, parameters such as the shape, position, or size of the clamping protrusion 1221 can be adjusted to meet more design requirements of the spray arm assembly 10.

[0079] In some embodiments of this utility model, such as Figure 4 As shown, at one end of the elastic arm 122 (e.g. Figure 4 The lower end of the elastic arm 122 shown extends along an arc away from the protrusion of the spray arm 11 in the direction of the clamping protrusion 1221. Therefore, after the clamping member 12 clamps the tableware, the elastic force of the end of the elastic arm 122 where the clamping protrusion 1221 is located can be increased, thereby further improving the stability and reliability of the clamping member 12 in clamping the tableware.

[0080] In some embodiments of this utility model, such as Figure 4As shown, the upper surface of the clamping protrusion 1221 is formed as a guide surface, which gradually extends towards the spray arm 11 from top to bottom. In this way, during the loading of tableware, the guide surface can guide the tableware, making it easier for the side wall of the tableware to be loaded between the elastic arm 122 and the clamping body 121, thereby reducing the difficulty of operation for the user and further improving the user experience.

[0081] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the elastic arm 122 is fixed to one end of the clamping body 121 (e.g., Figure 4 The lower end of the elastic arm 122 shown is provided with an anti-slip groove 1222, which is located on one side surface of the elastic arm 122 facing the nozzle 111 in a first direction (e.g., Figure 4 The upper surface of the lower end of the elastic arm 122 (shown in the diagram) has an anti-slip groove 1222 adapted to accommodate and limit the periphery of the tableware to be washed. Thus, the anti-slip groove 1222 can limit the position of the tableware, reducing the probability of it shaking during cleaning.

[0082] In some examples, the anti-slip groove 1222 can be formed by a downward recess on the upper surface of the lower end of the elastic arm 122. In other examples, such as Figure 4 As shown, anti-slip ribs are formed on the upper surface of the lower end of the elastic arm 122. There are multiple anti-slip ribs, and the anti-slip grooves 1222 are defined by the cooperation between adjacent anti-slip ribs.

[0083] like Figure 4 As shown, the clamping body 121 extends in the vertical direction, and the elastic arm 122 is connected to the clamping body 121 and arranged on the rear side of the clamping body 121. The elastic arm 122 is in the shape of an elastic plate. The length direction of the elastic arm 122 is parallel to the vertical direction and the width direction is parallel to the horizontal direction. The upper surface of the lower end of the elastic arm 122 is provided with multiple anti-slip ribs. The multiple anti-slip ribs extend in the horizontal direction and are arranged at intervals in the front-back direction.

[0084] In some examples, the clamping body 121 is a cylindrical shape extending along a first direction. In the direction from the first end 121a towards the second end 121b, the second end 121b of the clamping body 121 extends beyond the clamping protrusion 1221 towards the highest point of the protrusion of the clamping body 121. For example... Figure 4As shown, the highest point of the clamping protrusion 1221 is the position where the clamping protrusion 1221 is closest to the clamping body 121 in the front-back direction. This not only extends the length of the clamping body 121 and increases the sleeve length between the clamping body 121 and the spray arm 11, improving the connection stability between the clamping body 121 and the spray arm 11, but also facilitates the clamping body 121 and the clamping protrusion 1221 in cooperating to clamp the sidewall of the tableware to be cleaned.

[0085] In some examples, the second end 121b of the clamping body 121 is along (e.g.) Figure 4 The upper edge of the clamping body 121 shown in the figure) and the edge of the elastic arm 122 opposite to the first end 121a (as shown in the figure) Figure 4 The upper edge of the elastic arm 122 shown is generally flush with the upper edge. This further improves the connection stability between the clamping body 121 and the spray arm 11, and optimizes the structure of the clamping member 12, thereby improving the stability of the clamping member 12 in holding the tableware to be cleaned.

[0086] like Figures 1-2 As shown, the bowl basket assembly 100 according to a second aspect embodiment of the present invention includes: a bowl basket body 20, a water pipe 30, and a spray arm assembly 10 according to the first aspect embodiment of the present invention. The water pipe 30 is disposed on the bowl basket body 20, and the water pipe 30 is along a second direction (e.g., Figure 1 The second direction extends in the left-right direction shown in the figure, and the second direction is perpendicular to the first direction; the number of spray arm assemblies 10 is one or multiple ones arranged at intervals along the second direction, and the water inlet end of the spray arm 11 is connected to the water pipe 30.

[0087] like Figure 1 As shown, the water pipe 30 can be fixed to the dish basket body 20, for example, by snapping it into the dish basket body 20 or by fasteners. The number of spray arm assemblies 10 can be one, two, three, four, five, six, eight, ten, fifteen or more, etc. The lower end of the spray arm 11 is formed as a water inlet end, which is connected to the water pipe 30, and water is supplied to the spray arm 11 through the water pipe 30.

[0088] The dishwasher may also include a water supply pipe 400, one end of which is connected to a water pump. The inlet of a water pipe 30 is connected to the water supply pipe 400, and multiple spray arm assemblies 10 are spaced apart on the water pipe 30. Driven by the water pump, water inside the dishwasher can flow through the water supply pipe 400 and the water pipe 30 to the spray arms 11, and finally be sprayed out from the spray nozzles 111 to clean the dishes.

[0089] Furthermore, the dishwasher may also include a central spray arm 500, a water supply pipe 400 arranged below the dish rack body 20, the central spray arm 500 arranged below the water supply pipe 400, the water supply pipe 400 extending in a left-right direction, the right end of the water supply pipe 400 connected to a water pump, and the left end of the water supply pipe 400 connected to the central spray arm 500. The central spray arm 500 is rotatably connected to the water supply pipe 400, and a plurality of spaced-apart spray holes are formed on the central spray arm 500. A water pipe 30 is arranged on one side of the central spray arm 500 in the front-back direction, the water pipe 30 extending in a left-right direction, and the right end of the water pipe 30 connected to the water supply pipe 400. A plurality of spray arms 11 are spaced-apart on the water pipe 30 in a left-right direction.

[0090] According to the bowl basket assembly 100 of the present utility model embodiment, by providing the spray arm assembly 10 of the first aspect embodiment, the spray arm assembly 10 is provided with a clamping member 12 for clamping the tableware to be cleaned. This not only achieves effective fixation of the tableware to be cleaned, but also facilitates the spray nozzle 111 of the spray arm 11 to extend into the tableware to be cleaned, thereby improving the cleaning effect. By making the clamping member 12 detachably connected to the spray arm 11, the assembly and disassembly efficiency between the spray arm 11 and the clamping member 12 can be improved, the maintenance and replacement of the clamping member 12 can be facilitated, the assembly difficulty and maintenance cost of the spray arm assembly 10 can be reduced, thereby improving the overall performance of the bowl basket assembly 100.

[0091] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the bowl basket body 20 includes a plurality of first rods 21, and the water pipe 30 is provided with a limiting structure. The limiting structure cooperates with the first rods 21 to limit the relative movement of the water pipe 30 and the bowl basket body 20.

[0092] like Figure 5 As shown, multiple first rods 21 extend in the front-to-back direction and are spaced apart in the left-to-right direction. In the front-to-back direction, the first rods 21 extend undulatingly in the up-down direction. The bowl basket body 20 also includes multiple second rods, which extend left and right and are spaced apart in the front and back. The multiple first rods 21 and the multiple second rods are intersected and connected to each other, forming the bottom frame structure of the bowl basket body 20.

[0093] In some examples, the limiting structure may include a limiting block, a limiting hook, a limiting post, a limiting groove, and / or a limiting hole, etc.

[0094] In this embodiment, the limiting structure is combined with the limiting structure of the first rod 21 to limit the water pipe 30, thereby limiting the spray arm assembly 10 and improving the stability and reliability of the spray arm assembly 10 fixed on the basket body 20.

[0095] like Figure 5 and Figure 6As shown, in some embodiments of this utility model, the water pipe 30 includes a main pipe 31 and branch pipes 32, the main pipe 31 being along a second direction (e.g., Figure 5 The branch pipe 32 extends in the left-right direction (as shown in the diagram) and extends in the third direction (e.g., in the right-right direction). Figure 5 and Figure 6 (as shown in the front-back direction) extends, and one end of the branch pipe 32 (e.g.) Figure 6 The rear end of the branch pipe 32 shown is connected to the main pipe 31, and the water inlet end of the spray arm 11 is connected to the other end of the branch pipe 32 (e.g., Figure 6 The branch pipe 32 shown in the figure corresponds to the spray arm 11. The limiting structure is provided on the branch pipe 32, and the third direction is perpendicular to the first direction and the second direction.

[0096] In this embodiment, by setting multiple branch pipes 32, multiple spray arm assemblies 10 can be connected to the main pipe 31 through multiple branch pipes 32, reducing the probability of interference between the spray arm assembly 10 and other components of the basket assembly 100. Setting the limiting structure on the branch pipes 32 can facilitate the arrangement and forming of the limiting structure, and facilitate the limiting structure to cooperate with the first rod 21 for limiting, resulting in a more reasonable and compact structural layout.

[0097] like Figure 3 and Figure 6 As shown, in some embodiments of this utility model, the limiting structure includes a first limiting block 33 and a second limiting block 34, the first limiting block 33 and the second limiting block 34 being in a first direction (e.g. Figure 3 As shown in the diagram, the first limiting block 33 and the second limiting block 34 are arranged at intervals in the vertical direction, respectively abutting against the first rod 21 on both sides in the first direction. Thus, the first limiting block 33 and the second limiting block 34 can cooperate with the first rod 21 to limit the displacement of the spray arm assembly 10 in the first direction.

[0098] Specifically, the first limiting block 33 is arranged above the second limiting block 34, and the first rod 21 abuts between the lower surface of the first limiting block 33 and the upper surface of the second limiting block 34. The first limiting block 33 cooperates with the first rod 21 to restrict the spray arm assembly 10 from moving downward, and the second limiting rod cooperates with the first rod 21 to restrict the spray arm assembly 10 from moving upward.

[0099] like Figure 6 As shown, in some embodiments of the present invention, the first rod 21 extends along a third direction and a portion is bent toward one side in the first direction to form a bent portion 211. The bent portion 211 includes a first segment 2111, a second segment 2112 and a third segment 2113 connected sequentially along the third direction. The first limiting block 33 and the second limiting block 34 respectively abut against the two sides of the second segment 2112 in the first direction.

[0100] like Figure 6 As shown, a portion of the first rod 21 is bent downwards into a U-shape to form a bent portion 211. The first rod 21 may have one or more bent portions 211 arranged at intervals. Bending the first rod 21 can improve the rigidity of the first rod 21 and also facilitate the use of the bent portions 211 to support and / or limit the tableware and other items inside the bowl basket body 20.

[0101] In some examples, the first rod 21 also includes connecting segments that connect the two sides of the bend 211. The first segment 2111 and the third segment 2113 both extend in the vertical direction, and the second segment 2112 extends in the front-back direction. The upper ends of the first segment 2111 and the third segment 2113 are respectively connected to the two connecting segments. The lower ends of the first segment 2111 and the second segment 2112 extend downward and obliquely towards each other in the front-back direction. The two ends of the second segment 2112 are respectively connected to the lower ends of the first segment 2111 and the second segment 2112.

[0102] In this embodiment, by bending the first rod 21 downward to form a bent portion 211, and by abutting the first limiting block 33 and the second limiting block 34 against the upper and lower sides of the second section 2112 respectively, the overall position of the spray arm assembly 10 can be moved downward, reducing the height of the spray arm assembly 10 in the bowl basket assembly 100, making it easier to place tableware and improving the stability of tableware placement.

[0103] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the first limiting block 33 and the second limiting block 34 are in a third direction (e.g., Figure 6 The first limiting block 33 is located on the side of the second limiting block 34 facing the main body 31 in the third direction, and the first limiting block 33 and the main body 31 respectively abut against the two sides of the first segment 2111 in the third direction.

[0104] In this embodiment, by abutting the first limiting block 33 and the main pipe 31 against the two sides of the first segment 2111 respectively, the displacement of the spray arm assembly 10 in the third direction can be restricted, thereby improving the stability and reliability of the spray arm assembly 10.
